How much cake should I order for 20 guests?

Twenty guests is a small enough group that the cake can be planned closely around the actual celebration. The goal is to provide enough suitable portions without forcing a design that does not match the event.

Short answer

For 20 guests, do not choose a cake only from a fixed kilogram chart. Tell Moh Bakes that you need about 20 servings, whether cake is the main dessert, the design you prefer and your event date. The bakery can then recommend a practical size based on the cake's dimensions, height, decoration and intended portions.

Describe how the cake will be served

A family birthday with generous slices is different from an office event where cake follows a full meal. Mention the serving situation so the quote can be based on how the cake will actually be used.

Main dessert or one of several desserts
Adults, children or mixed group
Home, office or event venue

Choose a design direction before final sizing

A heart cake, tall round cake or themed children's cake may be built differently. Pick a genuine Moh Bakes reference, then let the size and decoration be adapted for the 20-person event.

Shape or style
Message or age
